>> brian, we're all products of our experience, of our environment where we come from. i have been tempered by that experience about war. what war means, the consequences, who has to fight it. all of that experience is part of me and how i look at policy, how i look at our foreign policy, how i look at our military policy, how i judge consequences, how the world sees us. their trust in our purpose, in our power. no question that much of the questioning i had done about iraq, ev before we went into iraq was conditioned by, tempered by that experience in vietnam and whatever i will ever do in my life, whether it's in politics or outside, those experiences shaped me just like anyone who has gone through war. those experiences shape you very much. and one of the things it does is it makes you less inclined, i suspect, to jump into war. it's easy to get into war, not very easy to get out as evidenced by the johnson tapes. and you need to think through these things, diplomacy is critically important especially in a complicated world that we live in today. i think something else is important here
